Descripción del producto

Cubic boron nitride cutting tools (CBN) have CBN, which is a synthesized material exceeded in hardness only by diamond. However, unlike diamond cutting tools, CBN cutting tools are stable at temperatures up to 1,**0 degrees F for machining hardened ferrous or superalloy materials of Rc *5 or higher and for machining some cast irons.

Higher CBN content in specific grades of cutting tools provide increased fracture toughness and resistance to abrasion. Cutting tools that have grades with more than *0 percent CBN content exhibit high thermal conductivity, excellent abrasion resistance, and exceptional toughness. High-content CBN cutting tools have grades, which are primarily used for machining case-hardened and through-hardened steels, superalloys, chilled cast iron, sintered metals, pearlitic gray cast iron, hard coatings, hardfacing materials and workhardening materials.

CBN cutting tools with grades less than *9 percent CBN offer low thermal conductivity, low diffusion wear and chemical inertness. Cutting tools with these grades are often used for finish cuts on hardened steels even with interruptions, hard powdered metals, nitrided steels, and hardened cast iron.
